A NEW end of season Ultra Challenge - in the 'Garden of England' - with a basecamp near Maidstone, parking & weekend camping options.


The main 50km looped route heads anticlockwise around the Kent Downs - starting on the North Downs Way to Blue Bell Hill, around picturesque Aylesford, and following the River Medway to Mote Park at halfway for a picnic. Along the Len Valley Walk to the majestic Leeds Castle, then the North Downs Way back to the showground finish line and celebration. 

Choose from the full 50km loop route, a 25km half challenge, or a 10km Maidstone Loop. All with a variety and some wonderful scenery & views - and easily accessible from London - there's a North Downs 50 Challenge for everyone!

Charity Sponsorship – you pay a small registration fee; do lots of fundraising and we cover the cost of your event place!

Mixed Funding – pay half of the event place cost yourself; fundraise a bit less and we pay the balance of the event place cost.

Self-Fund – you pay the full cost of the event place; fundraise whatever you want, with no set target or deadline, and there’s no cost at all to the charity!


When fundraising, we would advise that you set up a JustGiving page. It is the most effective way for you to fundraise! If you have any questions about this, please get in touch.
